  • Publication number: 20200256677
    Abstract: A gyroscope includes an atomic beam source to generate an atomic beam in which individual atoms are in the same state, a moving standing light wave generator to generate M moving standing light waves, an interference device to obtain an atomic beam resulting from the interaction between the atomic beam and the M moving standing light waves, a monitor to detect angular velocity by monitoring the atomic beam from the interference device and an accelerometer. The accelerometer acquires information on acceleration applied to the gyroscope and the moving standing light wave generator adjusts the drift velocity of at least M?1 moving standing light waves among the M moving standing light waves in response to the acceleration information.

  • Publication number: 20200043201
    Abstract: A method for calibrating a wearable device includes displaying an image with a plurality of pixels for each of three primary colors using the wearable device, and determining RGB and XYZ values for each of the plurality of pixels. The method includes selecting a subset of the plurality of pixels to form a group of grid points, and dividing the image into a group of tile regions, with each tile region including a grid point. Grid XYZ values are determined for each grid point, based on averaging XYZ values of all pixels in a corresponding tile region, and a grid RGB-to-XYZ conversion matrix is determined for each grid point. The method also includes determining a correction matrix for each grid point by multiplying an inverse of the grid RGB-to-XYZ conversion matrix for the grid with an sRGB-to-XYZ conversion matrix.
